The pistons are specifically designed for the Sportstter platform and improve both the tensile strength and the lifespan of the engine. By using an "inverted" piston floor, the compression ratio is effectively reduced, which leads to an optimized engine output. The end control of the specifications before assembly is the responsibility of the user to ensure that all components fit correctly.
